Demonstration of the Bezold Effect. The red seems lighter combined with the white, and darker combined with the black.
The Bezold Effect, also referred to as the "assimilation effect," is an optical illusion where a color's hue or value is affected by the color or colors surrounding it.
Discovery
The Bezold effect was first discovered by a German professor of meteorology, Wilhelm von Bezold (1837-1907), who discovered that a color may appear different depending on its relation to adjacent colors.
Description
When looking at a specific hue, it can appear to change in appearance depending on the colors that surround it. For example, a yellow box surrounded by blue will look darker than a yellow box surrounded by red. Often, the surrounded color seems to take on a tint of the color that surrounds it; red boxes surrounded by blue will appear more bluish than those surrounded by white.
Explanation
The reasons behind the Bezold effect remain a neurological puzzle.[1]
Applications
Knowledge of the Bezold effect is useful in fields such as graphic design, where artists can use combinations of adjacent colors to create the effect they desire.
